An embodiment of winding apparatus according to the present invention isshown in FIGS. 1, 2, 3, 4, 5, 6 and 7. A feeding web 1 is passing uponan empty mandrel M1 and winding around a mandrel M2. The mandrels M1 andM2 are rotatably supported by a pair of supporting arms 2, respectively.A fixing means and a cutting means are disposed above the winding meansas shown in FIG. 1. A traverse member 3 slidably engages with thetraverse guide 4 which is rigidly supported by frame F. A pair of shaftsS and 6 are disposed at the lower extended portion 7 of the traversemember 3. A pinion 9 and toothed wheel 10 are secured to the shaft 5,and a toothed wheel 12 and cutting wheel 11 are secured to the shaft 6respectively as shown in FIGS. 2 and 3. The toothed wheel 10 meshes withthe toothed wheel 12, and the pinion 9 meshes with a rack 13 which isdisposed under the traverse guide 4 as one body. The traverse member 3is connected with chain 14 at its upper portion. 'Ihe chain 14 traversesaccording to the actuating motion of actuating member (not shown) whenthe length of wound web around the mandrel becomes desired one,therefore, the traverse member 3 traverses along the traverse guide rod4. By this traverse motion of the traverse member 3, the pinion 9 isrotated by gearing with the rack 13, the cutting wheel 11 is rotated byrotation of the shaft 6 on which toothed wheel 12 is secured so as tomesh with the toothed wheel 10 which is secured on the shaft 5. Asmentioned above, during the transverse shifting motion of the traversemember 3, the cutting wheel 12 is cutting the supplied web by itsrotation, and after the respective transverse shifting and cuttingmotion of the traverse member 3 and the cutting wheel 12, the traversemember 3 returns to its original position according to return motion ofthe chain 14. A guide plate 15 is disposed at the end of the elongatedportion of the traverse member 3 at a right angle to the extendedportion of the traverse member 3. The guide plate 15 works as so-calledchopping board when the cutting roll 11 works to cut the supplied web 1.In FIGS. 1, 4, -5, 6 and 7 a punching tack holder 16 is secured to ashaft 17, and punching portion 18 is disposed at the forward end portionof the tack holder 16 so as to face to the empty mandrel M1. Tackassembly 19 has a U section with sharp edges and is inserted into thetack holder 16 so as to be able to be slid along a guide bar 20 bypushing member 21 which is actuated by a spring 22, when one tack of thetack assembly 19 is pushed out of the tack holder 16. A plunger holder23 is secured to a supporting member 24 at the corresponding portionupon the punching portion 18. A plunger 2S is disposed vertically in theplunger holder 23, and the bottom end of the lower elongated portion 26of the plunger 2S approaches the punching portion 18, and a spring 27for return motion of the plunger 25 to upward direction is disposedinside the plunger holder 23 as shown in FIG. 1. A set screw 28 works toset the supporting member 24 to the punching tack holder 16. A lever 29is pivoted to a shaft 17 and one end of the lever 29 forms an impacthead 30 for striking head 31 of the plunger 25 and the other end isarticulated to a piston rod 33 of fluid pressure cylinder 32. Both endportions of the fluid pressure cylinder 32 are connected with a transfervalve 34 which transfers the connection of fluid conduit with the otherend portions of the fluid cylinder 34 by an action of suitable actuatingmember, such as magnetic clutch, when the winding length of web aroundthe mandrel becomes desired length.

As shown in FIGS. 4 and 5, a fulcrum portion of the lever 29 is securedto the shaft 17 by key, and an end portion of the tack holder 16 isconnected by pin 35 to fulcrum cylindrical portion of the lever 29, anda groove 36 extending 0 angle around the axis of fulcrum portion of theholder 16 is disposed at the corresponding position of pin 35 as shownin the drawings. A control roll 37 is disposed at almost middle portionof the lower extended portion 7 of the traverse member 3.

By the above-mentioned punching tack members, when the length of woundweb around the mandrel M2 becomes desired length, `a suitable detectingmember (not shown) detects the wound length and actuates the transfervalve 34 so as to pull the piston 33 upward direction, then the lever 29rotates in a clockwise direction, however, the control roll 37 preventsdownward movement of the impact head 30 past the control roll 30. Aftertransverse movement of the traverse member 3, that is, after the impacthead 30 leaves the roll 37, the piston 33 further moves in an upwarddirection by the pulling action of the uid cylinder 32 and the impacthead 30 is pushed downward, while the tack holder 16 is also rotated ina clockwise direction around the pivot shaft 17. When the bottom portionof the tack holder 16 contacts the empty mandrel M1, through thesupplied web, the holder stops its rotational movement, however, theimpact head 30 of the lever 29 still rotates in a clockwise direction,because of the existence of the groove 36 which permits excess angularmovement around the pivot shaft 17. Therefore, the impact head 30strikes the head 31 of the plunger 25 so as as to strike and push outthe end tack of the tack assembly 19 from the tack holder 16, and thetack is pushed into the mandrel M1. According to the width of suppliedweb, plural tack holders can be arranged along the supporting shaft 38so as to insert punching tacks into the empty mandrel M1 at transverselydisplaced positions along the shaft 38. By the abovementioned punchingtack operation, the forward end portion of supplied web can be rigidlyattached to the empty mandrel M1, while the above-mentioned cutting roll11 Vis operating.

winding efficiency can be improved. It is one of thel functionalfeatures of the winding means of the invention, which is clearly shownaccording to the following description. In FIG. 8, -a central shaft 39is supported by a pair of frames 40, a pair of supporting arms 41 aresupported symmetrically by the central shaft 39. Supporting arms 41 areprovided with supporting portions 42, 43 and 44, 45 respectively, atboth end portions of the respective arms 41 symmetrical to the centralshaft 39. Rotatable shafts 46 and 47 are supporting by the supportingportions 42, 44 and 43, 45 respectively. Mandrels M1, M2 are supportedby the shafts 46, 47 so as to rotate together with the respective shaft.Sprocket wheels 48 and 49 are secured to the shafts 46, 47 respectivelyand a sprocket wheel 50 is loosely secured to the shaft 39. The sprocketwheel 50 is driven by a main sprocket wheel (not shown) and the sprocketwheels 48 and 49 are driven by the sprocket wheel 50 through chaindrivemeans 51 and 52, respectively, as shown in the drawing of FIG. 8. Afterwinding the forward end portion of the supplied web after aforesaidpunching operation and after winding length of supplied web around themandrel M1, the pair of supporting arms 41 are subjected to rotate 180by suitable turning mechanism, such as turret mechanism as shown in FIG.9. In FIG. 9 a turret plate 53 is rotatably secured to the central shaft39 and the driving shafts 46 and 47 are supported at the symmetricalposition of the turret plate 53 to the central shaft 39. The turretplate 53 is provided with worm wheel 54 as shown in the drawing and theworm wheel 54 meshes with worm 55 which is driven by the driving motor56 through ideal gearing 57. When the actuating means actuates thedriving motor 56, the turret plate turns 53 180, according to therotation of the driving motor 56.

After the turning motion, the position of the mandrels M1 and M2 arereversely changed, and the supplied web 1 is wound around the mandrelM1, while the mandrel M2 works as guide roller.

When the length of winding web around the mandrel M1 becomes of desiredlength, a driving shaft 57 is driven by an actuating member (not shown)and rotated to clockwise direction as shown in the drawing of FIG. 8. Asprocket wheel 58 is rigidly secured to the shaft 60 and an endlesschain driving means 14 passing guide sprocket wheels 59 disposed on theframe are driven by the sprocket wheel 58 so as to rotate the directionof arrows 62 in the drawing. As described above, the chain 14 is securedto the top portion of the traverse member 3 so as to drive along thetraverse guide 4. By this transverse movement of the traverse member 3,the cutter roll cuts 11 the supplied web along the traverse guide 4 asdescribed above. After starting this cutting operation, above-mentionedpunching tack operation is provided so as to Iix the forward end portionof the supplied web on the empty mandrel by tack, and after thispunching operation and its return operation, the driving shaft 60 turnsto the opposite direction so as to return the traverse member 3 to itsoriginal position. And after the length of wound web becomes somelength, the position of mandrels are changed reversely as mentionedabove, and when the length of wound web around the mandrel becomes todesired one, the cutting operation of web is actuated by suitableactuating means (not shown), and the abovementioned Successiveoperations are repeated.

In the above-mentioned operation, the timing of starting each operationshould be designed according to machine speed.

As described above, all operations are performed automatically, thewinding efficiency and quality of winding can -be improved remarkablyaccording to the method of and apparatus winding web of the presentinvention.
